Question

the length of a rectangle is 4 cm less than twice its breadth .if the perimeter of the rectangle is 22 cm ,find its length and breath​

Answer 1

Answer:

Let the length and breadth be L and B. Then it is given

L=2B-4 and equation 1

22=2(L+B)

L+B=11 equation 2

put the value of L from equation 1 in equation 2

2B-4+B=11

3B=11+4=15

B=15/3=5

put this value of B in any of the above equations you will get

L=6

Answer 2

Answer: LENGTH= 6 CM AND BREADTH= 5 CM
